For the bulk of 999, Akane, as June, acts cheerful and upbeat. She is optimistic, kind, intuitive and helpful to the best of her abilities, though she can be somewhat quirky and naive. She also appears to trust and believe in everyone, and refuses to let anyone get left behind or die, even if it's absolutely the only choice to proceed. True to the "Peacemaker" Enneagram of Personality she was based on, she values peace, love, and tranquility. Akane also believes that everyone could be friends if they talked it out and tried to understand each other's perspective more.
